Spodumene -Triphane

Best Known as Yellow Kunzite

General Information:

Triphane, the pale yellow gem variety of the mineral spodumene, is best known as the yellow version of Kunzite. Triphane’s name is derived from a word of Greek derivation meaning "three aspects" due to its clear trichloism.

Triphane was first found in Connecticut. But the first commercially significant deposit was discovered in 1902 in the Pala region of California, where Golden beryl was also first discovered. Triphane is often found in association with golden beryl , the other popular yellow gemstone. Today most triphane is mined in Brazil, Afghanistan, and Madagascar.

Triphane shows the best color in larger sizes. Stones should be at least ten carats to show the best color.

Triphane is relatively hard, however, it should be handled with care because, like diamond, it has a distinct cleavage which means a sharp blow, if it lands in the wrong place, can break it in two. Triphane should also be protected from heat and continued exposure to strong light which can gradually fade its color.

Care & Maintenance:

If there is excessive buildup a very soft toothbrush can be used, however beware of scratching the gold setting. Beware of Heat and Strong light because they can fade the color.
